Physicists score double hit in LED research
- wwarner 7y agoThe publication at arxive: https://arxiv.org/abs/1905.12227 https://arxiv.org/abs/1905.12227
- williamDafoe 7y agoQuite frankly I couldn't see the benefit. We already have solid state led lasers operating at THz speed. What is the actual improvement in this? Nick Holynak already demonstrated laser transistors more than a decade ago ...
- merlincorey 7y agoThe most interesting thing from this for me was hearing about LiFi, which is a networking technology I have never even heard of being deployed, but apparently is in some environments.
- eitland 7y ago+1 from me. To me LiFi seems interesting in a number of ways (disclaimer, this is just my understanding) : - Less interference - Harder to eavesdrop since it stops in walls - Higher transfer speeds
- skunkworker 7y agoSeems like it could replace the current infrared headphones/headsets.
- sgt101 7y agoMy understanding of LiFi : it's absolutely great apart from when the test room has bright natural sunlight.
- TheSpiceIsLife 7y agoThat does sound like a significant drawback to wide spread outdoors adoption, and some indoor areas too.
- WhiteSage 7y agoMy tv remote works with lights on, why wouldn't LiFi?
- TheSpiceIsLife 7y agoAt 11 mins in to this his TED talk Harald Haas talks about using Li-Fi to enable cars to communicate with each other. https://youtu.be/NaoSp4NpkGg?t=660 https://youtu.be/NaoSp4NpkGg?t=660
